As shown in fig. 1 to 4, an FPC board gantry plating jig may include an upper board jig 1, a plurality of metal clips 2 (14 are shown), and at least one copper plating jig 3. The upper plate jig 1 is made of non-conductive non-metallic materials, and the bakelite plate is adopted in the embodiment. The copper plating jig 3 is made of a conductive metal material, and the embodiment is made of a stainless steel mirror steel plate. The metal clip 2 is made of conductive metal material, and the metal clip used for binding documents by using office stationery in the embodiment has the specification of length 16mm and width 10mm, and the maximum paper clipping amount is 40 copies of 70 g. 4 or 8 fixing pin holes 101 with the diameter of 2.0 need to be drilled at specific positions on a product 100 needing copper plating, and the fixing pin holes are used for matching with a copper plating jig for alignment. Simultaneously, the rivet holes can be drilled additionally according to the requirements, and the fixture is used for reinforcing products and coppering.

The thickness of the upper plate jig 1 needs to meet the height of the metal clip 2 during operation, and the electric wood plate with the thickness of 12mm is adopted in the embodiment. The outer dimension requirement of the upper plate jig 1 is larger than that of the copper plating jig 3, so that the single side of the upper plate jig 1 is 30mm larger than that of the copper plating jig 3. The upper plate jig 1 is provided with a plurality of first hollow-out abdicating grooves 11 so as to abdicate the metal clamp 2. In the present embodiment, the number of the first undercut grooves 11 is 2, 10 and less, wherein the small size is 42mm x 46mm, and the large size is 112mm x 46 mm. The upper plate jig 1 is simultaneously prepared with 12 first rivet abdicating holes 12 having a diameter of 5.0mm for abdicating plastic rivets (not shown), which correspond one-to-one to the rivet holes (not shown) of the product 100. The upper plate jig 1 is provided with 8 metal cylindrical fixing pins 13 with the diameter of 1.95mm, and the height of the fixing pins is required to be higher than that of the copper plating jig 3 by 2. The fixing pin 13 of the present embodiment is 5mm higher than the table top. A plurality of inner grooves 14 are further formed in the periphery of the upper plate jig 1, and the inner grooves 14 are used for taking the copper plating jig 3 during operation. In this embodiment, the number of inner grooves 14 is two on each side, and the size thereof is 45mm (depth) × 35mm (width).

The thickness of the copper plating jig 3 needs to ensure certain smoothness and stability, and is not easy to bend and deform. The sum of the thicknesses of the two copper plating jigs 3 does not exceed the maximum non-deformable span of the opening of the metal clamp 2. In this embodiment, the copper plating jig 3 directly adopts a stainless steel mirror steel plate with a thickness of 1 mm. The outer dimension of the copper plating jig 3 is 50mm larger than the single side of the product. The maximum external dimension length of the copper plating jig 3 is determined according to the height of the liquid level of the copper plating tank body and the position of the conductive rod immersed in the tank body. The copper plating jig of the embodiment adopts a stainless steel mirror steel plate with the length of 650mm and the width of 350 mm. The copper plating jig 3 needs to make full hollow-out abdicating on the position of the metal clamp 3 and the product area. Namely, the copper plating jig 3 is provided with a second hollow abdicating groove 31 and a product hollow abdicating groove 32. The second hollow abdicating grooves 31 correspond to the first hollow abdicating grooves 11 one to one. In the present embodiment, the number of the second undercut grooves 31 is 2, 10, wherein the small size is 30mm by 30mm, and the large size is 80mm by 30 mm. The size of the product hollow abdicating groove 32 is 240mm 450 mm. The device can be used on single products with width of 250mm and length of 460mm at most. The copper plating jig 3 can be used for fixing products with the width of 250mm and the length of any length not exceeding 460mm by only drilling necessary fixing pin holes and optional rivet holes in the products. The periphery of the product is reserved with a single-side 5mm area which is covered by a copper plating jig 3 for fixing and conducting electricity. In addition, the copper plating jig 3 is provided with 38 yielding round holes 33 with the diameter of 2.1mm, namely a fixed pin aligning hole and a prepared second rivet yielding hole. The fixing pin aligning hole is aligned with the fixing pin hole 101 of the product for the fixing pin 13 to pass through. The second rivet abdicating hole corresponds to the first rivet abdicating hole 12 for the plastic rivet to pass through.

The working process of the present invention is described below: firstly, the alignment pin hole of 1 copper plating jig 3 is sleeved on the fixing pin 13 of the upper plate jig 1, then the product 100 with the fixing pin hole 101 drilled is taken, and then the alignment fixing pin hole is sleeved on the copper plating jig 3. Then 1 copper plating jig 3 is sleeved on the product 100, and the copper plating jig, the product and the copper plating jig are overlapped in a plate overlapping mode, and finally the metal clamp 2 is fixed around the copper plating jig 3, so that the assembly is completed. If the plate is worried about to fall off, plastic rivet reinforcement can be added according to the needs. The copper plating jig can be used only one, and 2 copper plating jigs are not needed for operation. During operation, only one copper plating jig and a product can be used for fixing by matching with the elastic metal clamp, and the plastic rivet can be added for fixing for more firmness due to the fact that a rivet hole position is preset. At this time, the assembled belt containing the product is fixed on a flying target of a gantry copper plating line operating line by a copper plating jig. When the fixture is fixed, copper plating operation can be performed only by screwing the conducting rod screw to clamp copper plating on two sides of the fixture. The copper plating jig ensures that the product is smooth, and the periphery of the copper plating jig surrounds the product to form a plating accompanying area, so that the copper plating uniformity of the product is improved due to the smoothness of the product during copper plating. And finally, after the copper plating operation is finished, the jig is dismounted, and the copper plated product can be taken down only by taking down the metal clamp 2 or additionally adding the plastic rivet.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
